Software

[nyggus]

Hi. SHould it be, "A and B software has been used to perform the analyses" (where A and B are software names)? Software is singular, but I noticed many used its plural form in such situations.

I'd say A & B programs have.... You will see the plural used sometimes, but most treat it as uncountable. If I did use 'software' in the sentence, I would keep it as singular.
